A novel inspecting system combining a tunable exposing unit for inspecting micro-cracks of solar wafers is proposed. With the infrared ray transmitting through silicon wafers, the inspecting images will be captured by a CCD camera, and the micro-crack defects from the images will be apparently appeared. So it can easier to precisely distinguish either micro-cracks or grain boundaries from the images...
A dual-confocal auto-focus sensing module for measuring defocusing positions of specimens in laser machining systems or inspecting devices is proposed. This sensing module can improve the detecting accuracy by analyzing and fitting signals from the difference between the dual optical paths, and miniaturize the optical apparatus with the superior integrated optical design. This auto-focusing module...
As perceived by consumers, the value of an eco-product can be enhanced by its product form in addition to physical product attributes. This paper develops a neural network (NN) and multiattribute decision making (MADM) approach for determining the design combination of product form elements that match a given eco-product value (EPV) and product image. A morphological analysis is used to extract form...
To extend the driving range of an electric scooter, the high efficiency direct-drive wheel motor has become an attractive alternative. For this reason, high quality silicon steel plates are applied to the wheel motor in order to reduce iron loss. However, finding a suitable steel plate with the characteristics of high efficiency, high output power and low manufacturing cost, is difficult. This paper...
Optical fiber communication has become mainstream in wired communication due to its low attenuation, low cost, and high bandwidth. However, optical fiber is light and thin, which makes the coupling procedure between fibers and optoelectronic components very complex and difficult. To maintain high transmission quality, it is imperative to develop a high-precision alignment technique for optical fiber...
